HAY cARRlER-TRACK HANGER.

SPECIFICATION forming part of Letters Patent. No. 387,142, dated July 31, 1888.

Application filed March 26.1888. Serial No 268,459. (No model.)

To aZZ whom it; may concern:

Be it known that we, WILLIAM H. BURN- HAM and JOHN H. MILLER, citizens of the United States, and residents of Batavia, in the county of Kane and State of Illinois, have invented new and useful Improvementsin Hangers for Tracks of Hay Carriers, of which the following is a specification,reference being had to the accompanying drawings,illustrating the to invention, in which Figure I is a perspective representation of a single hanger attached to the timbers of a barn and made to support a portion of the track to a hay-carrier. Fig. II is an enlarged eleva- I5 tion of the bracket, nut, and upper portion of the supportingrod; Fig. III, a plan or top view of Fig. II with nut removed; Fig. IV, an inverted plan view of the central portion of the bracket. Fig. Vis a side elevation of the semicylindrical nutremoved and the supportingrod.

The purpose of this invention is to provide hangers for the track to a hay-carrier, which may be adjusted to bring the track to any position required, permit the track to have a suitable lateral movement in either direction from a vertical position under the supportingnut, and to prevent the track from having a longitudinal movement. \Ne accomplish this by a two-Winged bracket, which is provided transversely on its central top portion with a semi-cylindrical seat, which has a slot made through it parallel with the wings of the bracket to allow the hanger-rod to pass through.

5 This rod by means of screw-threads is adjustable i u an elongated semicylindrical nut, which fits the seat in the bracket. The hanger-rod passes through the track and supports it by a head, which can be turned to adjust the track to any height or pitch desired. The wings of the bracket, being curved upward from the base, form strong supports with light metal, and the space between them gives ample room for the upward projection of the screw.

N N represent the two wings of the hangerbracket, which unite at M in forming a central support for a semi-cylindrical nut, O, the seat R having a contour corresponding to the semi-cylindrical part of the nut O. A slot, K, is formed through the base M of the bracket, parallel with the wings N, whereby the rod P may haveamovementinoneplaneonlyofabout ninety degrees for the purpose of carrying the track S laterally over the hay-compartment for the distribution of hay. The dotted lines VViudicate the deflected position of the track.

It has been the custom in fire-escapes to support the ladder by a semispherical washer, so as to give to it a universal movement of about twenty-three degrees of a sphere; but such a device would, it attached to a track, permit it to have a reciprocating longitudinal movement, which would make such track inoperative. Further, the nut which supports the ladder rests on the washer, and could not be used for a track-hanger, for the rod P could not be turned through such nut, because there is nothing to prevent the nut from turning with the rod.

It will be understood that the hangers are placed high up in a barn and are dilficnltto reach; hence the nut must not turn when the adjustment of the rod is made in it.

We claim as new In hangers for tracks for haycarriers, the bracket consisting of the central base, M, which terminates in the upwardly-projecting supporting-wings N, and has formed transversely in its top portion a semi-cylindrical seat, R, and a slot, K, formed throughit parallel with the wings N N, in combination with the semicylindrical nut O, the screw-threaded hangerrod P, adapted to pass through the nut and having a head on its lower end, and the track S, as specified.
